Description

  The present invention relates to a locking device provided in a vehicle glove box or the like.

  Japanese Patent Application Laid-Open No. 2007-285021 discloses a base, first and second stays supported by the base so as to be capable of reciprocating linear movement, a knob movable with respect to the base, and a first and a second when the knob is operated. A locking device is shown having a gear that synchronizes two stays in opposite directions.

However, the conventional locking device has the following problems.
Since the gear is used, backlash occurs between the first and second stays and the gear. Since backlash occurs, there is a possibility that the operation feeling is lowered, the gear teeth skip, and the gear is damaged.
Further, since the gear is used, the contact between the gear and the first and second stays is close to the line contact, and the load applied to the gear teeth is increased. Therefore, it is disadvantageous in design.
